Sry, un-called for remark.

But UK, FR DK, would not fit within TX.

Darwin was right.

Think twice before discounting American Hybrids.

Heritage update.

My maternal great grandmother, whom I met only once, at the age of two, was a red headed Alsatian Jew.

Update on my heritage.

Pennsylvania Dutch and Amish share a charactic of mine.

We have gaps in our front teeth.

Anyone have experience with these?

Off Topic.
Some in my family, after genealogical study, claim that Pattens are descended from Dutch; translated Shoe Maker.

Others claim that we're Irish; translated Horse Thief.

Found a new receiver: HopeRF RFM69W Transceiver Module - 433Mhz Version Product Overview: The RFM69W is a highly integrated RF transceiver capable of operation over a wide frequency range, including the 433, 868 and 915 MHz license-free ISM (Industry Scientific and Medical) frequency bands.Its highl...

p.s., @ 25 F your ice cream will resemble a Milk Shake.

Why bother: I have two refrigerators and never enough freezer space. US FDA recommends that meat be stored at 0 F. Chicken and beef satay fresh for 90 days at 25 - 30 F without significant bacterial growth (according to recent US AG studies). Fine with me. US FDA recommends meat be cooked @ 164 F fo...

And, check this out: • HopeRF's RFM23BP are highly integrated, low cost,433/470/868/915MHZ wireless ISM transceivers module. The low receive sensitivity(?120dBm) coupled with industry leading +30dBm output power ensures extended range and improved link performance. Built-in antenna diversity and sup...

Hacked an OS THGR800 and added a remote 433 MHz dipole. Works fine.

Also found MySensor Arduino Nano + NRF24L01 + DS18B20.

p.s., why is it called Domoticz when Domotica is Sp for Home Automation.

Dumb question from an ugly American.

Richard

I am familiar with Jean-Claude Wippler. But before I look very far into this, a couple questions come to mind.
I'm assuming that Domoticz handles multiple instances of RFLink Atmega 2560s.
I suppose I need another at 868mhz?

Thanks. New to me. Have to check that out asap.
I did find another recommended receiver:

Quasar QAM-RX1-433
http://fr.rs-online.com/web/p/modules-r ... m=742-4481&

And, I will poach the receiver from an Ambient console since I know it works.

But in fairness, it may not work with RFLink.

For antennas, I've tried:
17.3 mm vertical, helical, dipole, with and without 100x100 mm aluminum ground plane.

Or:
modify the sensor and remote the temp probe...

Or, I could modify the sensor and remote the antenna.

Or locate a sensor with a probe.

Richard

So far I've tested:
Receivers:
Aurel
Oregon Scientific (poached)
SYN480R
On order:
RXB6
Qiachip

Sensors:
Oregon Scientific THGR800
Acurite V2
Ambient F007TH

No luck.

But the Ambient console receives both refrigerator and freezer sensors.

Richard

Alternatively, the sensor could be modified with an 2 Watt amplifier.

I'm trying unsuccessfully to find a sensor or receiver that will RX/TX thru refrigerator doors. Thought about an LNA. May need an attenuator; 3 dB, 6 dB?

Some help exists to decode these signals using an RTL-SDR. See item #20:
